Comment 8 for bug 623708

David - That is an error condition that would prevent a 2nd eCryptfs mount from happening. I don't think that is the cause of the problem, since the 2nd mount attempt simply failed.

Have either of you manually mounted your encrypted home directory using the `mount -t ecryptfs /home/.ecryptfs/$user/.Private /home/$user/` method? I'm guessing that at some point a different filename encryption key was used to do a mount and now you're stuck with the duplicated directories (Templates, Videos, Ubuntu One, etc.) that are created by some magical component (to me, anyways) the first time you log in.
